Energy barrier for 1,2-hydrogen migration in benzylchlorocarbene
Abstract
The intermolecular-intramolecular rate constants derived from the thermolysis and photolysis of 3-chloro-3-benzyldiazirine in tetramethylethylene gave an excellent Arrhenius plot; an activation energy of 6.4 kcal mol–1(26.8 kJ mol–1) was obtained for the 1,2-H migration in benzylchlorocarbene.
